Solitary objects

Photography, by its nature, captures everything visible in a frame.
I want control over the visibility of elements in this frame.
This can be achieved by making unwanted elements invisible.
But I take a different approach.
I start with nothing, a visual void, and create the element I want to be visible from the ground up.
The result is an object that resides in fundamental solitude. And I wonder:

What makes it intresting?
How do I determine which object to create?
It can be anything.
Should it be an everyday object?
Or not?
Should it provoke context by essentially not having it?
How does the element of scale behave?
What else is there?
